Mason Jar Lid

ABSTRACT

A two-piece mason jar lid is described, with said mason jar lid capable of being secured to a mason jar in the typical manner using a threaded band or ring. The two-piece mason jar lid includes an annular lid component and a circular lid component that can be rotatably disposed within the annular lid component. Indicia and indicators disposed on the annular lid component and circular lid component work in cooperation, such that rotation of the circular lid component causes the indicator to be aligned with the desired indicia, to, for example, indicate a date upon which fermentation within the mason jar may be complete. The annular lid component or circular lid component can also include one or more venting channels to permit venting of fermentation gases, while preventing air from entering the mason jar.

FIELD OF DISCLOSURE

The present disclosure relates to apparatus used to seal mason jars to facilitate fermentation processes.

BACKGROUND

For more than 150 years, Mason jars have been used to preserve food. Over this time period, mason jar lids remained essentially unchanged—mason jars were secured by a unitary planar lid secured to the jar by an outer threaded ring.

In recent years, Mason jars have seen a resurgence and have been used and repurposed in many different ways. This renewed interest has also caused individuals to reconsider how Mason jars can be used for their original and related purposes—to prepare, store, and preserve food. Consumers' interest in mason jars and lid options continues to soar. Several new lid options have become available to facilitate interesting uses, but none provide the most efficient and convenient user experience possible.

SUMMARY

Improvements to the typical unitary planar lid are desirable to permit fermentation and to provide optimal user experiences. This disclosure describes improvements to and variations from the unitary planar lid that can be used to facilitate fermentation and/or better user experience.

The present disclosure describes a two-piece jar lid having an annular component and a circular component. The circular component can be disposed within the annular component and can be rotated to allow an indicator on the circular component to align with indicia on the annular component. Venting channels may also be present in at least one of the components of the jar lid, to permit fermentation gases to vent. Other embodiments are described herein.

DETAILED DESCRIPTION

Referring first to FIG. 1 , a two-piece jar lid 10 is shown. As shown in the separated view of FIG. 2 , the jar lid 10 includes a circular component 100 and an annular component 200. In practice, the circular component 100 can be releasably retained or disposed within the annular component 200 to form the jar lid 10. The jar lid 10 can be secured to a mason jar using a threaded band or ring, as is currently known in the art.

As shown in 2, 3, and FIG. 5 , the circular component 100 can include a raised knob 102 disposed on and projecting from the first or upper surface 106. The knob 102 is sufficiently sized to be capable of being grasped by a user to rotate or manipulate the circular component 100 (e.g. to release the circular component 100 from the annular component 200). The knob 102 located on the circular component IOU can also serve as an indicator in conjunction with indicia located on the annular component, as discussed below. In the embodiment shown in FIG. 3 , the first surface 106 is substantially planar. When installed onto a mason jar, the first surface 106 will be user-facing and can thus include a branding, graphic or other ornamentation 104 that will be seen by the user when in use.

The circular component 100 can also include a second or lower surface 110 opposite from the first or upper surface 106, which can also be substantially planar as shown in FIG. 7 (discussed below). One or more projections and/or grooves 108 can be formed in the circular component 100 between the first surface 106 and second surface 110. In an embodiment, the projections or grooves 108 can be formed on a side surface of the circular component 100. The one or more projections and/or grooves 108 can cooperate with projections and/or grooves disposed on the annular component 200 to facilitate secured but releasable disposition of the circular component 100 within the annular component 200, as discussed in more detail herein.

Referring now to FIG. 4 and FIG. 6 , the annular component 200 is configured in an annular or ring-like form. The annular component 200 defines an opening 202, with said opening 202 having a circular shape and thus also having a diameter. The annular component 200 includes a first or upper surface 205 and a second or lower surface 210 (shown in FIG. 8 ). The first surface 205 and/or second surface 210 can be substantially planar. When installed onto a mason jar, the first surface 205 will be user-facing and can thus include one more indicia 206 (e.g. for the purpose described below with reference to FIG. 15 ). In the embodiment shown in FIG. 4 , the indicia 206 represent the 31 days that can occur within a month. In other embodiments, the indicia 206 can instead represent months, years, or jar contents.

This disclosure refers to embodiments having a rotatable circular component 100, with an indicator (e.g. knob 102) being disposed on the circular component 100 and corresponding indicia disposed on the annular component 200. Similarly, an indicator may be disposed on the annular component 200, with indicia disposed on the circular component 100, such that rotation of the circular component still causes alignment of the indicator with the indicia.

During the fermentation process, gases are created and must be vented. Thus, for users that intend to use the jar lid 10 for fermentation processes, the jar lid 10 can include one or more vent holes or other means for venting, to permit unwanted gases to vent while simultaneously preventing air from entering the jar. More specifically, the circular component 100 and/or the annular component 200 can include one or more means for venting. In the embodiment shown in FIG. 4 , the annular component 200 can further include one or more venting channels 204. In the embodiment shown in FIG. 4 , four venting channels 204 are shown, but the annular component 200 can include more or fewer than four venting channels. While the jar lid 10 typically requires venting channels to permit fermentation, some non-fermentation embodiments of the jar lid 10 can include an annular component 200 with no venting channels. In some embodiments, a venting channel 204 disposed in the annular component 200 can be releasably sealed by the circular component 100 disposed thereon.

Referring again to FIG. 4 , the annular component 200 can include one or more projections and/or grooves 208 formed in the annular component 200 between the first surface 205 and the second surface 210 (FIG. 8 ). In an embodiment, the projections or grooves 208 can be formed on a side surface of the annular component 200. To ensure a snug fit between the circular component 100 and the annular component 200, a projection formed in the annular component 200 can mate with a groove in the circular component 100, or vice versa. Multiple projections and/or grooves can be utilized in this manner.

Referring now to FIG. 7 and FIG. 8 , the “underside” or “bottom side” of the circular component 100 and annular component 200 are shown, respectively. As discussed earlier, the circular component 100 can include a first surface 106 and a second surface 110. As shown in FIG. 7 , the diameter of the second surface 110 can be smaller than the diameter of the first surface 106, such that the first surface 106 extends radially out from the diameter of the second surface 110. As shown in FIG. 8 (which is drawn to scale in an embodiment) the diameter of the opening 202 can be sized to accommodate the smallest diameter of the circular component 100. As shown, the diameter of the opening 202 is sized to accommodate the diameter around which the projections and grooves 108 project and recede from the circular component 108. With such sizing, the projections and grooves 108 fit snugly and communicate with respective grooves and projections 208 disposed on the annular component 200.

As previously discussed and again shown in FIG. 8 , the annular component can have one or more vent holes 204. These venting channels or holes 204. The venting channels 204 can extend from the first surface 205 (FIG. 4 and FIG. 6 ) to the underside of the annular component generally reflected as second surface 210 and shown in FIG. 8 . As shown in FIG. 8 , the second surface 210 can have a recessed surface 212 disposed therein. In some embodiments, the venting channels or holes 204 can extend from the first surface 205 and terminate at the recessed surface 212.

FIG. 9 shows an alternate view of the components shown in FIG. 7 and FIG. 8 , with the “underside” of the circular component 100 and annular component 200 shown towards the top of the page. From the alternative perspective shown in FIG. 9 , the recess 212 within the bottom surface 210 can be better seen, as can the mating relationship between the projections and grooves 108 and 208. FIG. 10 primarily illustrates the “underside” of the jar lid 102 with the circular component 100 seated within the annular component 200. As can be seen, the second surface 110 of the circular component 100 seats flushly adjacent to the second surface 210 of the annular component. FIG. 11 depicts the top view of the combined jar lid 10 shown in FIG. 10 .

FIG. 12 and FIG. 13 show top and bottom views, respectively, of the circular component 100. As can be seen in these figures, the bottom surface 110 has a smaller diameter than the top surface 106. The diameter of the bottom surface 110 fits snugly within the recess 212 (FIG. 8 and FIG. 9 ), which is appropriately sized to accommodate the same. FIG. 14 depicts cross sectional views of the circular component 100 and the annular component 200, illustrating the location and disposition of the projections and grooves 108 and 208 that interrelate to securely retain the circular component 100 within the annular component 200.

FIG. 15 depicts three of many possible configurations 10 a, 10 b, and 10 c of the circular component 100 within the annular component. As seen, the circular component 100 can be rotated about its central axis within the annular component 200. A user can grab the knob 102 to rotate the circular component 100 about the annular component 200. The same knob 102 can include a tapered tip such that it also serves an indicator. For example, as shown in configuration 10 b, a user who secured the jar lid to a jar on July 9^(th) could rotate the indicator 102 to point to the “9” to indicate such a date. Similarly, if the same user wanted to indicate that the jar lid 10 was to be removed two weeks after July 9^(th), the user could grab the knob/indicator 102 and rotate the circular component such that the knob/indicator 102 pointed towards the “23”. Such a configuration 10 c would remind the user to check on the contents of the jar two weeks later, on July 23^(rd). As can be appreciated, the indicia shown in FIG. 15 can be used in many similar manners. Additionally, different indicia may be shown on the annular component, such as months, years, or recipes, and users can similarly use the knob/indicator 102 to point the indicator towards the indicia of their choice—the two component jar lid 10 permits the same.

Although the embodiment shown in FIG. 15 includes indicia on the annular component 200 and the indicator on the circular component 100, the opposite configuration is also possible—the indicator can be located on the annular component 200 and the indicia can be located on the circular component, such that rotation of the circular component still allows the desired indicia to be aligned with the indicator.
